The Leatt Hydration Core 1.5 is a lightweight and durable solution to wearing your hydration and essentials around your waist. It features a 1.5 litre bladder and bite valve, alongside a magnetic catcher that comes with the feed tube so it stays in place, as well as water bottle and waist belt pockets. AirLine back ventilation also ensures sweat is kept to a minimum and provides constant airflow to where it is needed most for day-long comfort.
